Prospect with gold not seen in country with canal (6)
I believe the answer is:
panama
'canal' is the definition.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for panama that I've seen before include "city" , "Hat woven from jipijapa leaves" , "Great canal in middle America" , "Wide-brimmed hat" , "What may be seen overhead" .)
